Drawing of rotating magnetic field in 3 phase induction motor diagram

An induction motor s rotor can be either wound type or squirrel cage type. An induction motor or asynchronous motor is an ac electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. Speed torque characteristics of 3 phase induction motor duration.

In this article we will try to understand the theory behind the production of rotating magnetic field for that we will first imagine one stator of an electric motor where three phase winding is physically distributed in the stator core in such a manner that winding of each phase is separated from other by 120 o in space. The stator of three phase induction motor is made up of numbers of slots to construct a 3 phase winding circuit which we connect with 3 phase ac source. When a 3 phase winding is energized from a 3 phase supply a rotating magnetic field is produced.

Because both the rotor and stator iron surfaces are smooth apart from the regular slotting and are separated by a small air gap the flux produced by the stator windings crosses the air gap radially. Rotating magnetic fields are often utilized for electromechanical applications such as induction motors and. This field is such that its poles do no remain in a fixed position on the stator but go on shifting their positions around the stator.

We arrange the three phase winding in such a manner in the slots that they produce one rotating magnetic field when we switch on the three phase ac supply source.

The production of rotating magnetic field in 3 phase supply is very interesting. The induction motor rotates due to the rotating magnetic field in 3 phase induction motor which is produced by the stator winding in the air gap between in the stator and the rotor the stator has a three phase stationary winding which can be either star connected or delta connected. Whenever the ac supply is connected to the stator windings line currents i r i y and i b start flowing.
